Let me start with saying many things said here are copied form my review of the Tans Red version, because these guitars have many things in common.
This guitar costs 179 euros, but looks like a guitar that could easily cost 10 times as much. The finish looks nothing like the picture on Thomann's website. It's actually more green than blue; the perceived color varies, depending on the light. This guitar would look even more great if it would have a matching headstock.
The body has a flawless, seamless binding all over the guitar. I don't know it it's a real binding or just paint, but I couldn't care less. Even the F-holes have the same binding!
I have another semi-hollow guitar, a Höfner, which is as light as a feather and quite loud when played acoustically. This guitar is not lightweight by any means. It actually feels rather heavy, and when you look into the F-holes it's clear why: there's a massive center block in the middle, and the sides of the body are solid wood too.
The lack of a scale prevented me to weigh the guitar. In any case, this is not a flimsy construction, which I appreciate very much.
The 'string-through' system has definitely something to do with the above-average sustain. Just like the Trans Red version this guitars is acoustically just above average, the guitar doesn't 'push much air'. It's enough for practicing though.
The neck is typical for a Telecaster model. It's not as thin as your typical Ibanez shredder, nor as thick as the ones found on a Gibson Les Paul. I think it's just perfect. It's a one-piece neck, so there's no scarf joint. Instead Harley Benton opted for two string trees to get the necessary angle. The string trees are the cheapest you can buy, but they appear to work well.
The neck was perfect out of the box. Not perfect was the position of the bridge, which was 0.5 centimeters closer to the last fret than the Trans Red version. As a result the guitar was impossible to intonate properly. I had to move the bridge slightly, and cut some of saddle springs in half to get it right. Fortunately I like to fix things.
The tuners were a bit stiff at first, but accurate. They loosen up quickly. The nut is well cut for strings up to 010-046. For anything beyond that all bets are off.
The fret board can use some lemon oil or, even better, Dunlop 02 'Deep Conditioner', which will bring back the beautiful rosewood color. In the end I even used a generic 'dark wood conditioner' which made the fret board even darker. Just a matter of taste.
On almost all guitars I own the action was too high for comfort 'out of the box' and this Trans Blue is no exception. Just take your time to adjust the saddles to your own taste and don't forget to keep the radius of the neck in mind.
The sound of the Wilkinson humbuckers comes reasonably close to what you would expect from a Tele, Slightly on the bright side when compared to a Les Paul, and with enough character of its own. Nice.
In short: apart from the misplacement of the bridge it is a keeper. If you are not comfortable doing work on your guitar yourself and the guitar is obviously faulty, just send it back. Thomann will do everything to make you happy.
